This study focuses mainly on potential skin abrasion risks that are likely to be caused by the interactive force on a contact surface between a human body and a physical assistant robot’s cuff, particularly when these robots are misused. In this study, we develop a novel method for evaluating skin contact states in order to estimate abrasion risks. First, a simplified cuff model is designed to conduct abrasion tests on a piece of dummy skin. The skin is pasted onto a dummy’s leg to simulate the human skin’s viscoelastic properties. Then, the edge condition of the contact surface is measured while the cuff model slides on the dummy skin. We conduct an analysis of the interactive force and displacement between the cuff model and dummy skin and several principal influential factors are examined during the evolution of abrasion-induced skin damage. These results are applied to evaluate the contact conditions between the robot’s cuff and human skin, which makes a significant contribution to estimating the risk of abrasion injuries for a physical assistant robot user.

Abstract

This study focuses mainly on potential skin abrasion risks that are likely to be caused by the interactive force on a contact surface between a human body and a physical assistant robot’s cuff, particularly when these robots are misused. In this study, we develop a novel method for evaluating skin contact states in order to estimate abrasion risks. First, a simplified cuff model is designed to conduct abrasion tests on a piece of dummy skin. The skin is pasted onto a dummy’s leg to simulate the human skin’s viscoelastic properties. Then, the edge condition of the contact surface is measured while the cuff model slides on the dummy skin. We conduct an analysis of the interactive force and displacement between the cuff model and dummy skin and several principal influential factors are examined during the evolution of abrasion-induced skin damage. These results are applied to evaluate the contact conditions between the robot’s cuff and human skin, which makes a significant contribution to estimating the risk of abrasion injuries for a physical assistant robot user.
